Washington -LRB- CNN -RRB- -- Attorney General Eric Holder says the Justice Department plans to expand a review of police tactics to update training , technology and other standards around the nation .

The aim , in part , is to produce broad national recommendations to enhance officers ' safety , help them deal with new threats and also boost the use of technology such as police car and body cameras .

In the wake of complaints about police handling of protests in Ferguson , Missouri , critics likely will also push for new standards to address police crowd control tactics and the use of force . The protests followed the shooting death of unarmed teenager Michael Brown by a Ferguson police officer in August .

Associations representing police officers and executives have supported the idea of a commission to review standards .

Holder , who speaks to a gathering of police officers in Little Rock , Arkansas , on Wednesday , plans to announce his support for such a commission to do the most expansive review of police tactics in 50 years .

Holder , in prepared remarks , said the goal of the ongoing review is to `` swiftly confront emerging threats , better address persistent challenges , and thoroughly examine the latest tools and technologies to enhance the safety , and the effectiveness , of law enforcement . ''

An ongoing review is already doing some of the work . But Holder says expanding it would `` consider the profession in a comprehensive way and to provide strong , national direction on a scale not seen since President Lyndon Johnson 's Commission on Law Enforcement nearly half a century ago . ''

Excerpts of his speech were provided by the Justice Department before delivery .

Holder 's speech is also intended to mark the 20th anniversary of a landmark crime law that created the federal COPS grants program , which funds community policing in cities around the country .
